Application filed iFebruar-y 11, 1924. Serial No. 692,081.

1 all whom it may concern 'Be it known that CHARLES M. CLARK, a citizenof the United States, residing at Havre de Grace, in the county ofHarford and State of Maryland, has invented certain new and usefulImprovements in Loose- Leaf Covers, of which the following is aspecification, reference being had therein to the accompanying drawings.7

The invention relates to loose leaf covers, and has for its object toprovide a device of this character formed from preferably a pliableheavy paper, and means for holding detachably a plurality of sheets ofpaper therein, for instance letters. The device is particularly adaptedfor holding correspond ence and forming a cover for the correspondenceso that letters may be easily filed in a letter file. V

A further object is to provide the cover with spaced apertures adjacentthe hinging seam thereof, through which apertures arms of a paperfastener eXtend and engage the upper sheet of paper within. the cover.The other arms of the fasteners engage the outer side of the'back of thecover, and the apertures allow the cover to be entirely opened whichremains in place.

for exposing the letters to view.

A further object is to provide removable fasteners adjacent the ends ofthe cover, either of which fasteners may be easily removed, therebyallowing any of the letters to be entirely exposed to view by foldingthe letters diagonally towards the fastener A further object is toextend. the apertures past the hinging portion of the cover and into theadjacent side of the back of the cover, whereby the-connecting arms ofthe jaws of the fasteners will not interfere with the front and back ofthe cover opening into position in the same plane.

Vith the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed, it being understood that changes inthe precise embodiment of the 'invent1on 7 may be made within the scopeof what is Figure 1 is a perspective'view of cover showing the sameclosed.

I Figure 2 is a perspective view of the cover showing the sameopen.

j Figure 3is a detail bottom perspective view of one corner of thecover, showing the clip jaw engaging the back of the cover.

Figure at is a detail sectional view taken on line 44 of Figure 1.

- Referring to the drawing, the numeral 1 designates the cover, whichcover is formed preferably from heavy paper of a flexible type, and isbent upon itself at 2 to form the frontcover 3 and the back cover 3".The cover is preferably adapted for holding a plurality of sheets ofpaper 4, for instance letters desired to be kept together, and filed ina conventional form of filing cabinet. Heretofore loose leaf covers havebeen provided with securing fasteners for letters, which fastenersextend through the cover and through apertures in the letters, howeverwhere conventional forms of covers are used, involving fasteners, theletters are mutilated and to remove a letter from the lower portion ofthe stack of letters, it becomes necessary to remove the upper lettersfrom the fasteners, which involves considerable time. It has also beenfound where fastener covers are used, the cover sections, which form thefront and back of the cover can not be straightened out to a position inthe same plane. To obviate this difficulty, the front 3 of the cover isprovided with T- shaped apertures 5, through which apertures the arms 6of the paper clips 7 extend and engage the upper side of the upper sheetof paper 4 within the cover. The loops 8 of the clips 7 engage the outerside 9 of the back 3 of the cover and consequently the paper sheets lare securely clamped within the cover as a whole, however the top 3 ofthe cover may be opened to the position shown in Figure 2, where it willbe in the same plane as the back 3 of the cover and consequently the topsheet 4 of paper is exposed for itsentire surface, and if the same is aletter, itwma'y be easilyread. It will also be seen that any of thesheets .4 may be pulled from the stack without removing the fastener'7,- thereby obviating the difficulty experienced with covers of thischaracter 7 where fasteners are used which extend 1 through apertures inthe sheets of paper. The transverse recesses 10 of the T-shapedapertures 5 receive the eyes 10 carried by the clip arm 6, when thefront side3 of the cover is in closed position.

The apertures 5 are sufficiently long wherebyrtheir ends 11 extendbeyond the hinging point 2 of the front and back of the cover, and intothe adjacent side'of the back 3? of the cover, therefore it will be"seen; that when the front 5 of the cover is leaf coveris provided,whichis simplein construction, will positively hold a plurallty of sheets ofpaper therein, 111 a manner whereby any of said sheets maybe removedwithout disturbing the other sheets, the cover will open entirely,andone wherein upon removal of one of the clips, for instance the lowerclip, letters' within the file may folded diagonally towards theremaining shoulders for ment of the cli V signature. 7
